I actually still do a fair amount of dev, but I've hired out for most of it. I turned to sales because I needed to really focus on selling the product I'd built.

If you're the type who likes learning new things, you'll like both. It's a new and valuable skill set that applies to other areas of life. Even if you're not an extrovert (I am certainly not), you find a style that works.

Several times I've been able to build and automate things that helped me do some very creative sales work. So having two skill sets was big.

So to answer the question, I like both and maintain interests in both.
